Function and Benefit Guide

1. Maintenance Displays provide fuel level, engine hours and oil

change interval information; plus high coolant temperature and low

oil pressure shutdowns.

2. Weld Process Selector Switch makes choosing between Stick, Wire

and TIG processes easy. Switch also auto matically changes polarity

with process selection to make sure the machine is easy to set with

little effort or knowledge.

3. Coarse Range Control. Four Stick/TIG and two Wire ranges are

available for output control. Stick/TIG ranges are designed to

electrode diameters (3/32, 1/8, 5/32 and 3/16-inch) making these

models very easy to set.

4. Fine Adjust Control makes it easy to fine tune amperage within a

coarse range. Set control above 7 for best power while welding and

to 10 for generator-only use.

5. Engine Control Switch is used to start the engine and then select

between Run/Idle and Run.

6. Glow Plugs assist in cold weather starting.

7. 120 VAC and 240 VAC Covered Receptacles with Circuit Breakers.

Note: For matching plug, order #119 172.
